Fine-tune for pH & acid loading recommended

The old calculator only did alkalinity arithmetic. These account for the lime consumed neutralizing acidic water and acidic bottom mud.

Low pH means free CO₂ that consumes lime before alkalinity can rise.

Estimate only. For low or untested alkalinity, confirm with a water test before dosing. Liming is not permanent — alkalinity declines over time with acid loading.
